corlando52 Posted November 12, 2011 Report Share Posted November 12, 2011 I have a AVIC Z1 that has been upgraded to a Z3. I never bought the GEX P10XMT Traffic Module because I didn't want to pay a fee every month. Now it seems most navigation systems, even the low cost ones, are including Free traffic information with their units. My question is this... Is there a way for Z owners to get free traffic updates? I would be willing to buy another add on unit if necessary. Thanks! Chris Quote Link to post Share on other sites

Chris I suspect they use TMC (Traffic Message Channel), a function of RDS radio which is not supported on the American Z1/2/3 models, only the European HD1/HD3 versions Quote Link to post Share on other sites
